The authors report a series of 60 cases of renal cancer observed over
a 10-year period. Patients consisted of 35 women (58%) and 25 men (42%
), with a mean age of 52 years (range: 21-72 years). The clinical feat
ures were polymorphic, dominated by loin pain (76%), haematuria (75%),
a lumbar mass (46%), alteration of the general state (30%). The diagn
osis was established by ultrasonography in 58 patients and CT scan in
38 patients. The mean tumour diameter was 11.5 cm (5-25 cm) and two ca
ses presented bilateral tumours. The tumour was located in the upper p
ole in 40% of cases and was mid-renal in 30% of cases. The time to dia
gnosis ranged from 2 months to 3 years. Staging reflected the advanced
stage of the cancer. Treatment was surgical for 53 patients (88%). A
lumbar incision was generally performed (83%). The surgical procedure
consisted of nephrectomy and regional or hilar lymph node dissection.
Nephrectomy was simple for 27% of patients, radical for 69% of patient
s and partial for 4% of patients. The postoperative course was marked
by one death due to pulmonary embolism, and a stercoral fistula in 2 p
atients. Histological examination of the specimen showed clear eel ade
nocarcinoma in 92% of cases. The tumour weight was often considerable,
with a maximum of 3.750 kg. The lymph nodes removed were invaded in 5
0% of cases. The mean follow-up was 46 months (12 to 120 months). Foll
ow-up was normal at 3 years for 23 patients (43%) and at 10 years for
4 patients (8%). Tumour recurrence in the renal compartment was observ
ed in 3 patients after 3 years. Asynchronous metastases occurred in 10
patients (23%). The mean interval to metastases was 20 months (4 to 3
6 months).
